JAMES R. ANDERSON, OF LONAOONING, MARYLAND.

AXLE-LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 244,782, dated July 26,1881.

Application filed May 10, 1881.

To all whom it may. concern:

Be it known that 1, JAMES R. ANDERSON, a citizen of the United States,residing at Lonaconing, in the county of Alleghany and State ofMaryland, have invented certain new and usefulImprovementsinWheels; andIdo hereby declare that the following is afull, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

The object of this invention is to adapt the invention shown in myPatent No. 240,000, granted April 12, 1881, to wooden, partly wooden,and metallic or other than one-piece hubs; and to this end thisinvention consists in a solid lubricating axle-box adapted forapplication to such hubs, substantially as hereinafter specified andclaimed.

1n the accompanying drawings illustrating my invention, in the twofigures of which like parts are similarly designated, Figure 1 is atransverse vertical section, in perspective, of a wooden wheel providedwith my improvement; and Fig. 2 is a longitudinal vertical section of ahub provided with my said improvement.

The wheel and hub a may be of any approved construction. The bore of thehub may be straight, tapered, or otherwise shaped, to receive acorresponding pipe or box, b, into which fits the similarly-shaped axlearm or nib 2. This box b is made solid, with a flange, c, at rightangles thereto, a head, d, parallel with said flange, and a shell, e,connecting the two. A pin or lug, f, extends rearwardly from the flangec, and said flange, shell, and head (I are preferably made somewhatthicker than the pipe 'in order the better to resist concussion. Theshell, head, and flange 0 form a chamber, g, at the end of the pipe b,which I utilize as a lubricant-receptacle, from which lubricatingmaterial is supplied to the axle. Access is had to this chamber throughan opening, h, which is normally tightly closed by a slide, i, projectedoutwardly into the closed position by a spring, j, in the shell is,formed with or attached to the shell cor flange 0. This opening alsosnbserves the purpose of permitting the manipulation of a linchpin orother axle-fastenin g, Z. The box (No model.)

or pipe b, its flange a, head d, shell 0, and pin f are made in onepiece by casting in suitable molds, and constitute, in connection withthe sprin g-slide, my improved lubricatin g axle-box. This axle-box isapplied to a hub by fitting the pipe 12 in the bore of the hub,providing recesses therein to receive the flange c and pin f and shellk, and securing the pipe by a nut, n, on its threaded inner end. Whenthe pipe is to be other than a straight tube it may be made separatefrom the lubricant-chamber, and after being inserted in the hub-bore itwill be connected to said chamber by a tight joint.

In casting my box I may cast loosely in the lubricant-chamber a washer,0, to be interposed between the flange c and linchpin, to take the ifdesired. When the pin and shell is are opposite the box will be mostsecurely retained hence I prefer to use such pin.

The nutn may have a recess, a, for an axlewasher, n

What I claim is- 1. A wheel provided with a hub the axle-box of which ismade with the dust-tight lubricatin g-chamber g, having anautomatically-closed opening'therein, and the pipe I) connected withsaid chamber, substantially as described.

2. A hub, a, combined with the one-piece selflubricating axle-boxcomposed of the lubricating-chamber g, having the self-closed opening,and adapted to receivethe hub-attaching devices, combined with the pipeb to receive the axle, substantially as described.

3. The combination of the pipe I), flange 0, head at, shell 6, pin f,and spring-slide z, substantially as described.

4. The combination, with a hub, of a pipe, b, a lubricating-chamberreceiving the axle-securing device, a spring-closed opening to saidchamber, and. a nut, n, to fasten the pipe in my own I have heretoafiixeil my signature in the hub, substantially as described. presenceof two witnesses.
